Abstract

Ein Überlastschutz für eine Kraftmeßvorrichtung ist besonders platzsparend gestaltet und erfordert einen geringen Montageaufwand, indem der zweiteilige Lastaufnehmer (27), dessen zur Einleitung der zu messenden Kraft dienender erster Teil (56) mit dessen zur Weiterleitung der zu messenden Kraft an einen Meßwandler dienenden zweiten Teil (57) durch zwei Lenker (58, 59) parallelogrammartig verbunden ist, in der Form zusammenhängender Materialbereiche eines einstückigen Materialblocks ausgebildet ist, wobei insbesondere der diese Materialbereiche voneinander abgrenzende materialfreie Bereich (55) durch eine dünne Schnittlinie gebildet ist. Ein die beiden Teile (56, 57) miteinander in Eingriff haltendes vorgespanntes elastisches Element (78) ist in einer Ausnehmung (81) des zweiten Teils (57) angeordnet.
